I would really like to be able to take a longer trip on it, but this Sporty as its geared ain't cutting it.

The 1600 at 80 is pulling 3100 rpms. The Sporty is around 4000, same as my ex wife's Honda Sabre 1100.
There is a lot of wide open (boring)roads in Texas and would like to drop the cruising RPMS down some.

Travelling at 90 or 60 we should all wear ear plugs, anywhere except around town. The science was done forty years ago and they are the best tuning aid known to mankind. Life on a ride out will be much more comfortable and the many extraneous noises we are all subjected to while riding, including that happy purring engine, will be reduced to more comfortable levels. The false impression that the engine is screaming will be dealt with and plugs come at just a few cents a pair. Much more effective than changing gearing. The only changes I have made to my Harleys is to shorten gearing for improved performance, not lenghthen it!

I run a 30T on mine. That 3200-3300 RPM range sounds about right for 75 MPH.
I like to keep my Sportster in that range, I find 3000+ is where it's happiest.
I wouldn't put a 32 on a 1200. I would on a converted 883 that still has the 883 primary gearing.
29-30 will knock it down about 3.5%, 29 -32 would knock it down 10.5%

Mine seems fine at 3500, but with 200 miles between major cities I need better gearing.

And I think you can also drop your rear sprocket from the 68 tooth to a 65 tooth. Can anyone confirm whether this is possible for an 07 1200L?
